Title: Tension control device
Inventor: WAKIYAMA KOJI
IPC: G11B15/43
Filed: 1993-06-04
Abstract: PURPOSE:To obtain stable tape tension without providing a tension lever. CONSTITUTION:Information of a winding diameter of a tape-like medium 101 to be wound around a reel 2 and to be moved at a constant speed by a tape moving means 1 is obtained by a winding diameter detecting circuit 4. An error between a frequency of a frequency generator 3 and its expected value is obtained by an error calculation circuit 10. A signal proportionate to an output of the error calculation circuit 10 is outputted by a correction torque calculation circuit 11. A signal proportionate to an output of the winding diameter detecting circuit 4 is outputted by a back torque calculation circuit 5. A synthetic signal of the back torque calculation circuit 5 and the correction torque calculation circuit 11 is outputted by an addition circuit 12. Torque is generated on a motor 7 by a driving circuit 6 based on an output of the addition circuit 12, and inherent torque fluctuation of the motor 7 is canceled. In other words, fluctuation of the tape-like medium 101 in tension is suppressed.

Title: Sensor with hermetic sealing cover and its production
Inventor: KONDA NORIHIRO
IPC: G01N27/12
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To preserve a sensor part up to a time just before use without generating a change with the passage of time by providing a hermetic sealing cover capable of being opened at a time of use on the upper surface of a sensor main body and hermetically sealing the sensor part by the hermetic sealing cover. SOLUTION: A sensor main body 10 is a usual responsive type semiconductor gas sensor formed by using semiconductor fine processing technique. A hermetic sealing cover 20 is produced by a process wherein a hermetic sealing film 23 is formed on a silicon substrate at first and a heater wire 25 is subsequently formed thereon and a protective film 27 preventing the deterioration of the heater wire 25 is further formed thereon and the cutting flap hole 28 reaching the hermetic sealing film from the protective film 27 is succeedingly processed and, further, etching is applied to the rear surface of the silicon substrate to form a cavity housing the sensor part 7 on the upper surface of the sensor main body 10.  The rear surface of the hermetic sealing cover 20 thus produced and the upper surface of the sensor main body 10 are laminated and bonded, for example, under vacuum to cut off the sensor part 7 from the open air. When a current is supplied to the heater wire 25 just before use as a sensor, a part 24a to be deformed is warped by the thermal expansion difference between the hermetic sealing film 23 and the protective film 27 and a cavity part is opened at the part surrounded by the cutting flap hole 28.

CONSTITUTION:During carrying a preceding sheet S1', the second sheet carrying and rotating means 16 is rotated in preset seconds and stopped in the state that the trailing end of the sheet is left in the nip portion of the second sheet carrying and rotating means 16. Then, the second sheet carrying and rotating means 16 is rotated in the state that the leading end of a following sheet S2' is inserted into the nip portion, to simultaneously carry the preceding sheet S1' and the following sheet S2'. This allows a gap to be narrowed between the sheets S1', S2' and the omission of image information to be prevented or minimized.

Title: Film feeding device for camera
Inventor: INOUE AKIRA
IPC: G03B1/00
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent a focus from being influenced by a film deformation part caused in the flange of a film cartridge even after photographic film is left as it is in a camera for a long time. SOLUTION: The film is fed and controlled by a film feeding motor 11 and a signal in accordance with film feeding amount is outputted from a perforation detector 13 or a film encoder 14. In the case the camera is switched to a non- actuated state or it does not perform operation over a specified time, the film is moved by a CPU 16 in a 1st direction by a specified amount based on the film feeding amount signal. Meanwhile, according as the camera is switched to an actuated state or an operation instruction is inputted, the film is fed by the CPU 16 in a 2nd direction opposite to the 1st direction. Thus, in the case the exposure operation of the film is not performed over a long time, the film is moved by the specified amount so that a frame to be exposed next comes to a position where it is not influenced by the film deformation.

Title: Stopping device for recoding head of fish finder
Inventor: MURAO TADAFUMI
IPC: G01D9/00
Filed: 1985-06-19
Abstract: PURPOSE:To prevent an accident of a driving device from happening by providing a means which detects the position of a belt associatively which the belt. CONSTITUTION:The belt 2 is rotated normally at a constant speed by being driven by a driving motor 8. A magnet 10, therefore, comes close to a magnet switch 11 at a specific repetitive frequency. The magnet switch 11 is turned on or off when the magnet 10 comes close and sends its signal to a CPU 12. If the rotation of the belt 2 is stopped for some reason, the signal from the magnet switch 11 is ceased. Said signal is therefore disabled to be counted in the CPU 12 and a stop signal for stopping the motor is sent to a motor control circuit on the basis of the judgement of that. The motor stops with the stop signal and is powered off.

Title: Magnetic recording medium
Inventor: IZUMI TOSHIAKI
IPC: C08L67/00
Filed: 1985-06-21
Abstract: PURPOSE:To obtain a recording medium having a low coefft. of friction, excellent running performance and good magnetic characteristics by the constitution in which 20-110nm particles project at 10-50nm average height on the surface of a thin ferromagnetic film contg. cobalt and chromium on a substrate. CONSTITUTION:The thin ferromagnetic film consisting of the assemblage of the columnar crystal grains which are oriented approximately perpendicularly to the film plane and have 700-2,100Angstrom  average grain size is formed on the substrate. Said thin film contains cobalt and 18-23wt% chromium. The particles having 20-110nm average grain size deposit at 50-500 pieces/mum<2> density on the surface of the thin film. The coercive force decreases when the average grain size and density exceed the limit thereof. Since the particles deposit on the surface of the thin magnetic film, the coefft. of friction is low and the running performance is excellent. The magnetic characteristics are thus improved.

Abstract: PURPOSE:To prevent the generation of jam and the damage of a device in this image forming device using a long photosensitive recording medium by giving indicating of winding to take-up mechanism at the time of detecting the existence of the photosensitive recording medium on its carrier path, and waiting the termination of winding to release the lock of a cartridge take-out preventing means. CONSTITUTION:While an image forming device is operated to be in image forming action and a photosensitive recording medium 3 is successively wound onto a take-up roll 9, a control part 14 periodically takes in the detection signal of the photosensitive recording medium from an empty sensor 10 to perform empty check on whether or not the recording medium 3 exists. A judgment on whether take-up action is continued or terminated is thereby made. In the continued state, the take-up roll 9 is rotated to complete the whole winding of the recording medium on a carrier path. When the recording medium 3 is no longer detected and winding is terminated, the stopper 12 of cartridge pull out preventing mechanism 11 is pulled in. This prevents the take-out of a cartridge in the state of the recording medium 3 being left on the carrier path.
